ClinConnect Summary

This clinical trial is looking at how to help patients with high blood pressure, also known as hypertension, better understand and manage their condition. It aims to improve health literacy, which means helping patients access, understand, and use health information effectively. The study will test a new approach that includes different communication tools for doctors to use with their patients. The goal is to see if this intervention helps patients reach their target blood pressure within three months.

To participate, patients should be between 65 and 74 years old, speak French, and currently have high blood pressure that is not well controlled. They should also have a mobile phone for reminders about the study. The trial is open to patients who can read and write, and who are willing to be part of this research. Participants can expect to engage in discussions with their doctors using new techniques aimed at improving their understanding of their health. This study is important because better understanding can lead to better management of high blood pressure, ultimately reducing health risks.
